ANALYSIS OF SHALLOW WATER EXPERIMENTAL ACOUSTIC DATA INCLUDING NORMAL MODE MODEL COMPARISONS

摘要

As part of a propagation model validation exercise experimental acoustic and oceanographic data was collected from a shallow-water, long-range channel, off the west coast of Scotland. Temporal variability effects in this channel were assessed through visual inspection of stacked plots, each of which displays 120 echo records. From such data an average impulse response for the channel, at a variety of ranges, was established. The average impulse response was compared with simulations performed using the fast broadband normal mode model developed in the EC MAST III PROSIM project. Comparative results are presented.
